A letter sent by 48 reproductive justice, drug policy reform, women’s rights, and civil liberties organizations called on Attorney General Eric Holder and the Department of Justice to renounce a policy of enhancing a criminal sentence for crimes committed while pregnant.

The law specifically criminalizes “the illegal use of a narcotic drug while pregnant, if [a woman’s] child is born addicted to or harmed by the narcotic drug.” But Mallory Loyola was arrested Tuesday for exposing her child to amphetamine, which is not a narcotic.

Tennessee lawmakers proposed a dangerous new law that allows for prosecuting pregnant people, as a South Carolina woman was sentenced to 20 years in prison for allegedly killing her infant while breastfeeding.

The Tennessee state legislature gave final approval Wednesday to a bill that allows women to be charged with assault if they have a pregnancy complication after using illegal drugs. Advocates argue that the bill is so poorly written that it could subject any woman with a poor pregnancy outcome to criminal investigation.
